erigir sra :ins PATE TRAVERSE-MECHANISJNL GEA/INGL' I v Bejit known that It, Wnnmivr GoNNoLLY, a British subject, residing at" Blackley, city of Manchester, England, haveinvented'certfai'n new and useful Improvements' iii"l`rav-` erse-Me'clianism Gearing, of which' the following is a' specification.v

rlhis invention relaties to traverse motions for wire winding'machines actuated byl a' double threadl reversing' screw or a number of screws of different lengths. n Y y It consists of a plurality of double thread'- ed l'reversing screws of either different lengths or dieren't'pitch, o'r both arranged concentrically around a' single drive' (thus occupying a minimum amount of space), and not placed atl or split up over diere'iit parts of a machineYwith' 'separate drives; and traversing nuts thereon, any one" o'f'wliich can be thrown into'andlout ofv gear with the screws to stop oneof thetravers'ebars or permit the screw to be removed from its" bearings 'and' replaced by another screw'of different length or pitch without interi-eri ence with other working parts.

The invention will be fully described with reference to the accompanying drawings.

Figure l is a longitudinal section.

Fig. 2 is a transverse section.

Fig. 3 is an end elevation.

The apparatus is constructed with a suitable number of traverse screws, three screws A A A2 being shown in the present in stance. These screws are mounted in bearings in supporting frame'ends B around a central shaft C, each screw having a double or reversing thread a. The threaded portions a of the screws are of different lengths and consequentlygive different lengths of traverse to the nuts D which engage with them. .Y

One of these nuts D is mounted upon each screw and fits within the thread a and is carried by a nut box D. Itis provided with a shank cl journaled in a screw cap cl by which it can be 'moved to and fro to bring it into or out of mesh with the screw as may be required. The lower end Z2 of the nut box D is made flat to engage a slot c in the lcentral shaft C.

When any nut D is withdrawn from contact with its screw A, the traverse bar connected therewith is stopped and the screw may be withdrawn longitudinally from its bearings and another of different length or pitch be substituted therefor without inter- Specificato of Letters` Patent Patented Nov-.46, 1917.A

The pitch of the screws may be different instead of, or in addition to, making them of different lengths, so that if desired the traverse of one may be slower than that of another.

iN hen the machine is in operation, all three screws will be rotated simultaneously; and if all the nuts are in contact with theirrespective screws, then all the traverse bars will bc operated, but by withdrawing one or two of the nuts the corresponding traverse bars will remain stationary although the screw revolves. For example, assuming that the screws are cut for traverses 33;, 35,- and 1. Traverse mechanism gearing, comprising a central shaft; a plurality of doublethreaded reversing screws disposed concen* trically around said shaft; means for driving said screws from said shaft; a traveling nut box mounted on each screw; a nut movably tted in each nut box; and a rotatable screw cap associated with each nut to movel rality of adjustable nuts one carried in each l nut box, screw caps to adjust and retain the nuts in position, and means to prevent the nut boxes from rotating, substantially as described.

3. Traverse mechanism gearing, comprising a central shaft; a plurality of doublethreaded reversing screws disposed co-ncentrically around said shaft; means for driving said screws from said shaft; a traveling nut box mounted on each screw; a nut movably itted in each nut box; and a rotatable screw cap associated with each nut to move the same into or out of engagement with the threads of the adjacent screw.
